(D) They needed to decide to put the canal in another place.

Concept note-1: -In constructing the Panama Canal, American planners and builders faced challenges that went far beyond politics and engineering. The deadly endemic diseases of yellow fever and malaria were dangerous obstacles that had already defeated French efforts to construct a Panama Canal in the 1880s.

Concept note-2: -The Hay-Pauncefote Treaty of 1901 abrogated the earlier Clayton-Bulwer Treaty and licensed the United States to build and manage its own canal.
